Worst! Bought something for about $30 and returned it that day. The berkeley website showed that it was refunded, but my balance showed as if I was charged another $30! Tried speaking to a customer rep but they wanted information that was not on my online profile. HORRIBLE EXPERIENCE - charged $2.50 each time I spoke to someone AND MY PROBLEM WAS NEVER RESOLVED!
